Petresa vs PCI chem.
PCI doesn't offer international exposure, and Petresa is owned in majority by the largest petrochem company in Spain with operating plants on 4 contenents. Only Petresa could be connected to Siam.
Location of plant discription said about 1/4 mile off hwy30. PCI is several kilometers off hwy30, and Petresa's driveway is only about 1/4 mile off.
PCI is a public traded company and the LOI would have required a PR if they were part of Siam.
PCI would have also been required to PR a sublease of property if it involved any income generation, or asset alocation (property) to Alcar.
When you read the discription of who/what Siam investors are, you'll find it matches up well with Petresa's owners, and doesn't apply to PCI at all.
I submit my opinion that only Petresa could fit the site location discription, and have ties to Siam.
